RlVET-SETTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 394,723, dated December 18, 1888.

Applica i n fi ed October 26, 1388- $erial No. 289,226. (No model.)

To (LZZ whom it may concern:

Be it known that I, (LARK M. PLATT, of Waterbury, in the county of New Haven and State of Connecticut, have invented a certain new and useful Improvement in Rivet- Setting Machines, of which I declare the following to be a full, clear, and exact description, reference being had to the accompanying drawings, forming part of. this specification.

This invention is in. the nature of an improvement in rivet or eyelet setting machines; and the invention consists of a rivet or eyelet setting machine constructed, arranged, and combined in the manner hereinafter particularly shown, described, and claimed.

In the accompanying sheet of drawings, Figure 1 is a perspective of my machine, and Fig. 2 is a plan or top view in part broken away.

Similar letters of reference indicate like parts in both views.

Machines organized with reservoirs or hop- 1 pers, inclined chutes, receivers, and plunger-s for the purpose of setting rivets and eyelets by means of which buttons may be fixed to garments, or the rivets alone be inserted, are numerous and old, and they have been repeatedly patented, and to a large extent they are public property. 'lheret'ore to such machines, in a broad sense, I do not claim any exclusive right; but, in combination with the several elements which go to make up a rivet or eyelet setting machine, particularly when employing a twisted chute or raceway, my invention consists of the particular construction and arrangement of the spring-jaws of the receiver A.

In detail the receiver is provided with an arm, a, which may or may not consist of the two parallel pieces of metal shown in the drawings; but obviously this supporting-arm may be made solid from one 'piece of metal. Vith either construction the arm is pivoted to the supporting-frame B of the machine, and its front end is provided with two springjaWs, b and 0, between which jaws is, formed a slot, 0, and this slot, which is a material part of my invention, extends from or about the place at which the foot (I of. the chute I) rests upon the jaws I) and c to the front end of the jaws, where they are curved and beveled to form the cup-shaped receiver A. The upper edges of the spring-jaws Z) and 0 throughout the length of the slot are preferably beveled, as atf.

To restore the jaws l) and c after the receiver A has been "forced open by the action of the plunger of the machine, either the elasticity of the steel of which the jaws are formed may be relied upon, or, if desired, any suitable kind of spring may be employed for that purpose.

To the rivet or eyelet setting machine, to which is attached the receiver hereinbefore described, is titted an inclined chute or raceway, I), which extends from the hopper or reservoir E to about the rear end of the slot C of the receiver or its spring-jaws b and c. This chute is twisted, as at g, so that a rivet entering at the upper end of the chute point up is delivered at the lower end point down. Now, since this point would project downward through the slot 7! in the lower end of the chute and come in contact with the arm or springs l) and c of the receiver A, and either clog the descending rivet in the chute or clog the receiver A by not presenting its point truly in the receiver, the slot C is provided, through which the point may depend. The beveled edges of the slot C facilitate the entry of the point of the rivet into the slot, and the rivet being carried in an upright position into the receiver A, through which it is thrust by the descent of the plunger F of the machine, the beveled edges f of the arms I) and c acting as guides to receive and steady the head of the rivet and to assist in conveying it to the receiver in the proper position.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In combination, in a rivet-setting machine, the twisted chute D and an arm, a, pivoted to the supporting-frame of the machine, and provided at its front end with spring-jaws b and 0, between which is a slot,

0, and at the end of which is the receiver A, as and for the purpose described.

2. In a rivet-setting machine, the pivoted 5 arm a, provided with two elastic jaws at the front end, constituting'a cup-shaped receiver at their outer ends, and a slot, 0, between said j aws, its sides having beveled edges 1) and c, as and for the purpose described.
